Seems like update 0.41.4 also displays the type of Pokemon, or maybe it’s the type of that Pokemon’s attack, using little icons when capturing Pokemon.

Scratch that! It seems that update 0.41.4 is kind of a bit bigger than it seems. Those “icons” that appear when you’re trying to catch a Pokemon actually relate to the “Rewards” you have earned. What used to be medals on your character page are now split into medals and rewards. The medals are the same old medals as before, but the rewards give you bonuses. Such bonuses currently give you a catch bonus to specific types of Pokemon, ranging from +1 to +3.

I’m not sure how significant Pokemon Rewards are, but they can’t be bad to have if you’re trying to catch a rare Pokemon of that type.
